WebAs the pH drops, coral reefs will lose their color, fish eggs, urchins, and shellfish will dissolve before maturation, kelp forests will shrink, and the underwater world will become gray and featureless. It is expected that color and life will return after the system re-balances itself, but it is unlikely that mankind will be here to see it.
WebSep 18, 2024 · Sea urchins can be found in rocky intertidal zones and kelp forests. Slow growth can be attributed to the lack of coelomic fluid acid–base balance compensating for the pH 7.6. They can be found all along the Pacific coast of Mexico, up to Alaska, living at depths of up to 525 feet. WebSea urchins graze kelp and may reach population densities large enough to destroy kelp forests. Sea otters prey on urchins and thus control the numbers of kelp grazers.An urchin barren is an area of the subtidal where the population growth of sea urchins has gone unchecked, causing destructive grazing of kelp beds or kelp forests (specifically the giant …
